I might follow spark and block him.
Futurist, I totally agree with most of your points (not necessarily the way you frame them), but I think you're thinking in a 'perfect world' solution. I work in elearning design, we work in the cloud, and upload and download tens and tens of gigs each day. Each raw Photoshop file we use is 100-200megs each, because of version control and risk reduction, you'll save maybe 4-5 copies of the same thing each day as you work, and upload these to the cloud as you go.
We would love to use file compression when we interface with clients, but the reality is that all of your government departments, and most of the large corporates have systems that don't accept files other than *.jpegs due to what else can be hidden in other types, and the onerous nature of security scanning if they tried to protect against all file types. So hence we're stuck using a filetype where the compression isnt very good, and working in document types that aren't very efficient and bloat our bandwidth because most business systems wont accept anything else.
Agree with 'in a perfect world files would be smaller' disagree that this is actually implementable, as companies are numpties whose individual policies often work against the good of the overall group and ultimately ... themselves.
